**EXAMPLE WITH CALCULATION STEPs:**

**STEP-1**

**(A)**Concrete volume in cum = Volume of casting (Length x Breadth x Height) in m

**= 10x1x1m (Assume) = 10 cum**

**(B)**Dry Volume Factor for Concrete = 1.54* Wet volume of concrete mix is

**54 % higher than**dry volume

**SETP-2**

**(C)**Concrete wet volume in cum =

**(A)**x

**(B)**

**= 10 x 1.54 = 15.4 cum**

**Concrete Ratio = ( Cement :Sand :Aggregate)**

**(Assume) = 1 : 1.5 : 3**

**i.e. M10-(1:3:6), M15-(1:2:4), M20-(1:1.5:3), M25-(1:1:2), M30-(1:1:1.5), M40-(1:1.62:2.96)**

Sum of Ratio = (Cement + Sand + Aggregate

**)**

**= (1+1.5+3)= 5.5**

**SETP-3**

**(CV)**Required Cement Volume in cum =

**(C)**x (Cement Ratio/Sum of Ratio)

**= 15.4 x (1/5.5) = 2.8 cum**

**Cement in Bag = (CV) / 0.034722**

**= 2.8/0.034722 cum = 80.64 Bags*** Volume of 1 Bag Cement is

**0.034722 Cum**

**(SV)**Required Sand Volume in cum =

**(C)**x (Sand Ratio/Sum of Ratio)

**= 15.4 x (1.5/5.5) = 4.2 cum**

**Sand in Cft = (CV) x 35.3147**

**= 2.8 x 35.3147 cum = 148.32 Cft*** 1 m3 =

**35.3147 Cft**

**(AV)**Required Aggregate Volume in cum =

**(C)**x (Aggregate Ratio/Sum of Ratio)

**= 15.4 x (3/5.5) = 8.4 cum**

**Aggregate in Cft = (CV) x 35.3147**

**= 8.4 x 35.3147 cum = 296.64 Cft*** 1 m3 =

**35.3147 Cft**

**FAQs: **

What is Dry Volume Factor for Concrete ?

**54 % higher than**wet volume so, When we calculate the mix proportion of concrete it should be multiplied with 1.54, its call Dry Volumn Factor of Concrete

What is Cement, Sand & Aggregate Ratio ?

**M10-(1:3:6), M15-(1:2:4), M20-(1:1.5:3), M25-(1:1:2), M30-(1:1:1.5), M40-(1:1.62:2.96)**
